What is Service In PSTN Requesting Internet Services (SPIRITS)? stephenraj 18-July-2008 02:13:49 PMComments www.ietf.org/html.charters/OLD/spirits-charter.html Posted by saqlain231 References: http://www.IETF.org, RFC 3136 http://www.IETF.org, RFC 3298 Posted by snjysanjay05 SPIRITS and Internet Call Waiting (ICW) provide a set of SIP extensions that do the opposite of what PINT does. It allows events on the PSTN to initiate events on the Internet. The most famous application for SPIRITS is called “Internet Call Waiting”. Lina wants to talk to Jerry, but Jerry is using his phone line for dial-up modem access. SPIRITS provides the standards for the PSTN to locate Jerry’s IP address, notify Jerry’s ISP that a call is pending, and push a web page or panel to Jerry’s web browser that says something to the affect of: “You have a telephone call pending. You may: 1. You may take this call over the Internet using a SIP phone on our computer 2. You can have this call forwarded to your telephone voice mail 3. You can have an appropriate announcement played to the caller 4. You can refuse the call and send a busy signal to the caller 5. You can exit your internet services and have the call ring your POTS telephone Posted by george99 The purpose of the SPIRITS protocol is to support services that originate in the cellular or wireline PSTN and necessitate interactions between the PSTN and the Internet.On the PSTN side,the SPIRITS services are most often initiated from the Intelligent Network (IN) entities.Internet Call Waiting and Internet Caller-ID Delivery are examples of SPIRITS services, as are location-based services on the cellular network.
